在 object数组的时候,要注意好类型的转换.

------java.lang.NumberFormatException: For input string 解决方法--------------------------------------------------------
字符分割异常转化字符或输入字符问题

public List<?> findAgencyArSumDetail(
		SettlementAgencyARDetailResult headInfoArResult) {
		String sql = "SELECT CNTR_SIZE||CNTR_TYPE AS containerSizes,"
				+ " COMPANY_CDE AS companyCode,"
				+ " FULL_EMPTY_IND AS fullEmptyIndicator,"
				+ " EXP_IMP_IND AS expImportIndicator,"
				+ " SOC_IND AS socIndicator,"
				+ " COUNT(*) AS containeraCount,"
				+ " SUM(FEE_AMT) AS toTalNum,"
				+ " FEE_PRICE AS feePrice"
				+ " FROM CBS_SET_DOC_AG_CNTR "
				+ " WHERE SVVD_ID=:svvdId"
				+ " AND PORT_CDE=:portCode"
				+ " AND COMPANY_CDE=:companyCode"
				+ " AND SO_COMPANY_CDE=:SOCompanyCode"
				+ " AND FEE_TYPE=:feeType"
				+ " AND ACT_FLAG=:actualFlag"
				+ " GROUP BY(CNTR_SIZE||CNTR_TYPE,FULL_EMPTY_IND,SOC_IND,EXP_IMP_IND,FEE_PRICE,COMPANY_CDE)";
		SQLQuery querys = (SQLQuery) cbsModuleRepository.getSessionFactory()
		.getCurrentSession().createSQLQuery(sql.toString());
	 
		querys.setParameter(SettlementContant.SVVD_ID,
				headInfoArResult.getSvvdId());
		querys.setParameter(SettlementContant.PORT_CODE,
				headInfoArResult.getPortCode());
		querys.setParameter(SettlementContant.COMPANY_CODE,
				headInfoArResult.getCompanyCode());
		querys.setParameter(SettlementContant.SO_COMPANY_CODE,
				headInfoArResult.getShipownerCompanyCode());
		querys.setParameter(SettlementContant.FEE_TYPE,
				headInfoArResult.getChargeCode());
		querys.setParameter(SettlementContant.ACTUAL_FLAG,
				SettlementContant.ACTUAL_FLAG_Y);
		List<Object[]> list = querys.list();
		SettlementAgencySumDetailResult agencySumDetailResult = null;
		List<SettlementAgencySumDetailResult> queryList = new ArrayList<SettlementAgencySumDetailResult>();
		for (Object[] object : list) {
			agencySumDetailResult = new SettlementAgencySumDetailResult();
			agencySumDetailResult.setContainerSizes((String) object[0]);
			agencySumDetailResult.setCompanyCode((String) object[1]);
			agencySumDetailResult.setFullEmptyIndicator((String) object[2]);
			agencySumDetailResult.setExpImportIndicator((String) object[3]);
			agencySumDetailResult.setSocIndicator((String) object[4]);
			agencySumDetailResult.setContaineraCount((BigDecimal) object[5]);
			agencySumDetailResult.setToTalNum((BigDecimal) object[6]);
			agencySumDetailResult.setFeePrice((BigDecimal) object[7]);
			queryList.add(agencySumDetailResult);
		}
		return queryList;
	}

注意循环遍历放到 List中..

这里还有关于HQL中在字符串的拼接问题.

      第一种:

+ " commBl.billBasicUuid= " + docHead.getBusinessReferenceUuid()
+ " AND commBl.companyCode = '" +docHead.getCompanyCode()+"'"
+ " AND commBl.commissionMode '" +arItem.getChargeCodeGroup()+"'"
+ " AND commBl.commissionType '" +arItem.getChargeCode()+"'"

hql.append(" WHERE commBl.billBasicUuid=:businessReferenceUuid");
		hql.append(" AND commBl.companyCode =:companyCode");
		hql.append(" AND commBl.commissionMode=:chargeCodeGroup");
		hql.append(" AND commBl.commissionType=:chargeCode");

	第二种:

Query query = cbsModuleRepository.getSessionFactory()
				.getCurrentSession().createQuery(hql.toString());
		query.setParameter(SettlementContant.BUSINESS_REFERENCE_UUID,
				settlementHead.getBusinessReferenceUuid());
		query.setParameter(SettlementContant.COMPANY_CODE,
				settlementHead.getCompanyCode());
		query.setParameter(SettlementContant.CHARGE_CODE_GROUP,
				settlementAR.getChargeCodeGroup());
		query.setParameter(SettlementContant.CHARGE_CODE,
				settlementAR.getChargeCode());

跟上边的可以比较一下,这里例举2中拼接的例子.
